Abstract (en)
[origin: US2010139993A1] A lobed bushing is provided for a track assembly of a track-type machine. The track assembly includes a first chain and a second chain coupled together with a track pin. A bushing, defining a longitudinal axis, includes a central bore oriented along the longitudinal axis and extending from a first end of the bushing to a second end of the bushing for receiving the track pin. The bushing includes a first lobe positioned at a first location about the longitudinal axis and a second lobe positioned at a second location about the longitudinal axis that is less than about 180° from the first location. The first end of the bushing has a substantially cylindrical shape.
